T aZZ whom it may cofic'erie:

Be it known that I, WRIGHT RHODES, a subject of the Queen of GreatBritain, residing at Manchester, in the county of Lancaster, England,have invented new and useful Improvements in or Applicable to Apparatusfor Stripping and Cleaning Flats Used in Carding-Engines, of which thefollowing is a speci- This invention relates to the means for strippingand cleaning the flats used in what are called revolving-flatcarding-engines, and has for its objects, first, simple and efficientmeans for stripping and cleaning from such flats the adhering cottonfibers, neps, and other impurities which have not been effectivelyremoved by the stripping-comb when the flats are at work, and, secondly,removing the so-stripped-ofi cotton fibers, neps, and other impuritiesfrom the strippingroller, as hereinafter explained,automatically by arevolving circular comb, thereby keeping the said stripping-rolleralways clean and in efficient working order while at work.

The manner in which my said invention is to be performed or carried intopractical effect will be readily understood on reference to the twosheets of illustrative drawings hereunto annexed and the followingexplanation thereof.

Figure 1 on the drawings is an elevation of my improved apparatus; Fig.2, a vertical transverse section of the same through the line A Blooking from the left, and Fig. 3 a similar view takenthrough the line CD looking from the right. Fig. 4 is an elevation of a modification ofthe same, and Figs. .5and 6 are detached views hereinafter moreparticularly referred to.

My apparatus consists principally of a central shaft a, upon which twocast-iron disks 1) and b are fastened, one near to each end, at therequired distance apart, according to the width of the Wire on theflats. At equal distances from the centers of these disks 1) b and in astraight line with the center of the saidv shaft a and parallel witheach other bearings are formed in these disks to receive the end pivotsor shafts of two rollers c d of small diameter, made of wood or othersuitable material,one of which, 0, is covered with a suitablecard-stripping fillet, the other, d, with salt No. 726,090. (to model.)

one or more rows of bristles, set in spirally. At the one end (which Iwill call the driving end) of each roller a small gear-wheel or pinion0* d is' fixed on the shaft, which engages or gears with a larger wheel6 of same pitch fixed on a stationary short boss or tube f, which latteris bored to receive the said central shaft or and in which the same isfree to revolve. This stationary boss or tube f forms the bearing forthe central shaft a atone end and also the bearing for the wholeapparatus at one end by having two sides fiattened and fitting into thesteps of the ordinary fiat-stripping brush brackets g, (see alsodetached view, Fig. 5,) or other suitable means may be adopted forfastening or fixing this boss. The two small wheels or pinions' 0 andd", fixed at the end of the strippingroller and bristle-brush, gear, asaforemen tioned, with the large wheel 6, fixed on the inside of thestationary boss or tube f, in which the central shaft 0, revolves, andno matter in what position the apparatus may be these pinions beingalways at equal distances from the axis of the central shaft and diskwill always remain in gear. The fact of the two disks b b being fixed onthe said central shaft and having bearings formed in a parallel line tothe center of the said shaft and being parallel to each other andcarrying the said stripping-roller c and bristle brush (1, which latterare both geared by the small ,pinions with the stationary wheel e,causes the stripping-ro1ler c and the bristle brush d to revolve ontheir own axes and also at the same time to be carried around thecentral shaft in the same direction, as hereinafter explained. A groovedband-pulley h, fastened to the central shaft (1., drives the same in thedesired direction, as shown by the arrows, at a positive speed, causingthe aforementioned two disks to revolvejwith it. The bristle brush d andstripping-roller 0 being geared at their ends with the aforementionedlarge stationary gear-wheel e, fixed on the stationary boss or tube f,are caused thereby to revolve on their own axes at a positive speed inthe desired direction at the same time'they are carried around thecentral shaft a in the same direction as they are revolving on their ownaxes. When at work, the apparatus therefore revolves in such a mannerthat the band-pulleys.

said stripping-roller c and bristle brush d alternately strip and brushthe wire of the flats it (see Fig. 2) in an efficient manner by having adouble action or movement on the wire of the fiatsthat is, an upward orlifting and at the same time a forward movement. Different speeds can begiven to the apparatus by using different sizes of driving A settingring or collar '5 (see Fig. 1) fits on the said stationary boss or tubef for setting and keeping the same in position. A circular revolvingcomb 7c is attached in a suitable position by forming bearings in eachdisk 22 b at equal distances from the center of the stripping-roller cand the center of the disks to receive the end pivots or shaft of thesaid circular comb. This circular comb it receives its rotating motionin the desired direction by means of two intermediate or carrier wheelsl P, revolving freely on a short stud m, which latter is fixed to thedisk, in the following manner: A small pinion or gear-wheel fixed at oneend of the shaft of the circular comb, engages or gears with the larger,Z, of two carrier-wheels, free to revolve on the said short stud. Tothis carrier-wheel another and smaller wheel or pinion Z is pinned orpegged, (both wheels being free to revolve together on the short stud,)the pinion Z engaging or gearing with the large stationary wheel 6. Whenthe disks Z) b are caused to revolve by being positively driven by theband-pulley h, fixed on the central shaft, the small pinion Z on theshort stud m, which gears with the large stationary wheel 6 on thestationary boss or tube f, is carried around the said large wheel e andalso at the same time is caused to revolve on its own axis and beingpinned to the other and larger gear-wheel Z and revolving together onthe said short stud and the larger wheel Z again being geared with thesmall pinion la at the end of the circular comb 70 to rotate-in thedesired direction and in such a manner and at such a suitable andquicker speed than the stripping-roller c is revolving that the saidcomb k, which being set into the wire of the card-fillet of thestripping-roller 0 will strip or clear the saidstripping-roller-automatically of the cotton fibers, ncps, 660., takenfrom the flats, thereby keeping the said stripping-roller 0 always cleanand eflicient to perform its work and while the apparatus is in motion.This comb 7c is also carried around the central shaft at the same timeas it is revolving on its own axis. The comb 70 consists of a thin steelshaft or other suitable material, into which two or more rows of steelteeth, bent or shaped into a half circle, or nearly so, are inserted atequal distances apart and in such a position as shown in Fig. 2. Whenthis circular comb 70 gets full of cotton fibers, &c., or nearly so, thestrips of cotton fibers collected by it are removed by the attendant.This comb may be made to lift out of its bearings for cleaning the same.The bristle brush (1 is made rather larger in diameter than thestripping-roller c to enable the bristles to penetrate deeper into thewire and brush out the dust from the bottom of the foundation or clothof the flat-clothing n. The apparatus can of course be set or adjustedby the adj Listing-screws or arrangement in the ordinary stripping-brushbrackets in the same manner as any ordinary stripping-roller. At theother end of the central shaft a bush f or step is placed upon the saidshaft a, and is fastened to it by a setscrew. This bush is ofcorresponding thickness to the stationary boss or tube at the other endof the central shaft, and the said shaft and bush revolve together inthe ordinary flat-stripping-brush steps or brackets g. I also attain thesame or similar results by the following arrangement: Instead of havingthe aforementioned short boss or tube in which the central shaftrevolves stationary or fixed, as described, I may allow the same (theboss) to be free to revolve or loose in the bearings or steps of theordinary flat-stripping-brush brackets 9. (See Fig. 4.- and detachedview, Fig. 6.) The said short boss or tube f is in this case madewithout the two flat sides, but perfectly round to revolve in the stepsor bearings of the ordinary brackets 9. Upon this loose boss or tube thelarge gear-Wheel e is fixed, as before, and the same engages with thetwo small pinions e and 61 fixed at the end of the stripping-roller andthe bristle brush. A grooved band-pulley is fastened on the said looseboss and drives the same at a positive speed in the opposite directionto which the stripping-roller c and bristle brush cl are required torevolve, which causes the large gear-wheel c, fixed on the said looseboss f, to engage with the pinions fixed on the stripping-roller c andbristle brush d, and thereby causing them to revolve in the opposite anddesired direction at a positive speed. At the same time a slow forwardor revolving movement around the central shaft is given to the saidstrippingroller 0 and bristle brush (1 by a grooved band-pulley h fixedat the other end on the central shaft and driving the same (andconsequently also the two disks 1) b upon which the two rollers aremounted) at a suitable positive speed in the same direction as thestripping-roller and the brushare revolving. This second arrangement, asabove described, requires an additional driving-pulley h and requiresthe short boss or tube to be made round (without the two flat sides) andfree to revolve in the ordinary steps g of the usualfiat-strippiug-brush brackets. The short boss f is driven positively bythe band-pulley h and the central shaft a is also driven positively byanother bandpulley W. I therefore prefer my first arrangement, as fullydescribed, as it only requires one grooved band driving-pulley to drivethe whole apparatus and can be applied to any card without anyalterations or additional driving-pulley than the usual means of drivinga flat-stripping brush.

ceases e s The advantages of my apparatus are an efficient double-actingtwo-speed movementfor removing or stripping and brushing the cot tonfibers, neps, and other impurities and preventing the so-called feltingor accumulation of cotton fibers and other impurities in the flat-cardclothing.

I claim as my invention- 1. Apparatus for cleaning flats ofcardingengines, consisting of a main shaft, rollers adapted to come intocontact with the flats, shafts on which said rollers are mounted andadapted to revolve about the axis of the main shaft in combination witha comb mounted to revolve about the main shaft and adapted to clean therollers of fibers substantially as described.
